Cort positioned the KX300-OPCB at the upper end of the KX Series, pairing a spalted maple top on a mahogany body with a bolt-on hard maple neck and a jatoba fretboard. The Open Pore Cobalt Burst finish was offered as one of two open pore sunburst options in the line.
The guitar carried a 648 mm (25.5") scale length across 24 frets, with a 400 mm (15.75") fretboard radius and white binding. Hardware was finished in black nickel throughout, anchored by a hardtail bridge with string-through-body stringing and die-cast tuners. Pickups were an EMG Retroactive Super 77 set — dual humbuckers in the classic zebra open-coil format — controlled by a three-way toggle switch with one volume and one tone control. Strings were fitted from the factory as D'Addario YB EXL110.
Owners sourcing replacement parts — including bridge saddles, tuner buttons, or nut stock sized to the fretboard — should consult a qualified luthier or guitar technician who can verify exact tolerances against the physical instrument.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
